OK, I have seen several threads here, concerning image retention problem, sometimes marked as screen burn. So I thought we could collapse into one general thread on this subject.
So, LCD screen does not have image burn problems. Image burn is name for persistent effect. What we have with our Primes is image retention. This effect is caused becouse liquid crystals in LCD gets used to its certain possition...
For example, if you have some bright background, and you leave it unchanged for about 10-15 minutes, than run some grey screen picture, you will see "ghost" of the background image in the app.
This effect can be seen in many screen technologies. S-IPS and AMOLED are widely used ones on tablets and mobile devices. They both suffer from this effect.
There is actualy big chance you won´t even notice that. Prime turns it screen off after some time, and when you use your device you are probably actually doing something, meaning you are dynamically changing the screen, so image retention has no time to take place.
In everyday use, problems could occur when you use SW keyboard for a long time, or for example game menu controls, etc.
The most important thing is, this is NOT PERSISTENT. Image retention of this type should dissapear after while, you can speed it up by either turning screen off or displaying plain white image for a while.
I believe none of our tablet displays are immune to this. In fact, even glory iPad 1&2 displays are not immune. Neither was my HTC Diamond screen. (Yes, pretty old, but it has nice VGA screen). Sometimes I get navigation cursors retained after reset, even for few minutes (on my HTC Diamond)... So I believe we just need to live with this effect. Most of the time, you won´t even notice it.
But we can share our experience. I have not notice any image retention untill today, when I needed to discharge my Prime more quickly, so I maxed brighteness (IPS+ on) and leave it in home screen on for about 15 minutes. Than I started YouTube app, and on its grey load screen, I clearly seen ghost of my homescreen background. I immediatelly retried lauchning YouTube app, but it was all gone. If curious, or if you want to replicate this, my homescreen image is the default with tree, most yellow-ish like I believe autumn sunset version

Think that is the root of your ghosting issue there, would not call that normal operation at all to leave it maxed out for 15mins. The display is super bright and I dont think even outdoors you need max IPS+ to adequately use the tab.
Well, if I am right, it sould have nothing to do with brighteness level. Like I said, it is different effect, it is not burned. But maye thrucomming light intensity has some effect on the crystal polarisation...
Thanks for the post, I get this effect with my Nexus One as well. The notification bar from having the phone in portrait mode shows itself at times in landscape.

Actually LCD panels can get screen burn, I have had two LCD HDTV s that had it. But those were first gen LCD HDTV s.
You shouldn't see anything like it on LCD screens of today. If what your saying is true then why isn't the status bar in ICS (or honeycomb) ghosting for everyone?
I've done some tests recently after finding this issue on my Galaxy Tab 7.0 Plus. It was VERY dramatic on that tab. Only a few seconds on one screen, change to a screen that is mostly gray and the image persistence was there for quite a while. And it was a strong persistence. Not just a faint image. You could easily read text and see images. The pictures in the following thread show it.
http://forum.xda-developers.com/showthread.php?t=1437445
But after having this issue, I ended up testing some other tabs I have. I've seen the issue on my Kindle Fire's (I have 3 of them). I have a Lenovo Thinkpad Tablet and have not seen the issue there. I also have a Transformer Prime and I do see it faintly on the prime, generally on the right side of the tab when holding in landscape (with power button on top). I also see it sometimes on my 30" Dell IPS monitor.
I guess the point is, it is more common than you think. But some screens may exhibit the problem more than others. That Galaxy Tab 7.0 Plus (that specific one) exhibited it far worse than anything else I've seen.
I've decided not to worry about it. If it's happening to yours and it happens very quickly and doesn't go away quickly, perhaps your display is worse than the norm. But I would expect all of these displays to show some level of image persistence. Return it if it bugs you, but accept the fact that they all may have this issue to some degree.
Thanks to the OP for this post.
I'm deciding between a tf201 or a samung tab 7.7 but I've been reading a lot of reports that users are getting backlight bleeding and others are not.. what is the actual stand on this, is the backlight bleeding normal or just common?
People defend it by saying that even the ipad2 has bleeding, I've checked 3 ipad2's from relatives and none if it had any backlight bleeding including a single ipad1 and 2 iphone4's.
For TN based displays I understand its normal for it to have bleeding.
As an ex-Asus fanboy, there definitely is a light bleed issue. Most prominently around the right and bottom sides of the tablet. IF you look around at the forums about light bleed issues, you'll notice that people who have had the issue say "I'm not on my 4th prime" or something similar. It's an issue with shotty quality control.
I bought a prime and had a light bleed issue. Majority of that light bleed could only be seen when the screen was black. However, it is very significant light bleed. Other tablets or IPS devices that have light bleed are similar, but just not as pronounced. Asus really redefined light bleed
I traded in my first Asus Prime and received a second one (BC) from the same store. It had light bleed in almost the exact same location, and in some cases worse. None the less, I took that back and just kept my money. Hopefully a galaxy tab 2 or Iconia A700 or TF700 or IPAD 3 will serve me better for the $500 I spent.
Bottom line -- if you're going for a prime, you're most likely going to get light bleed (chances are slim you won't). And after spending a week with it, it gradually got worse.
I might try to buy one again at the end of February to see if they improved the quality.

Of course there "SHOULD" not be any backlight bleeding. No manufacturer wants to produce a display with light bleeding from the sides.
The reality is that most Primes suffer from this and it is up to the user to live with it or not. The one I had did have some bright spots along the lower edge of the screen and I would have put up with it had it not been for the constant reboots.
For me its not gonna be acceptable considering the price and the touted S-IPS since I've never personally seen one with backlight bleeding. I guess I have to wait it out.

Utility of a device is always a matter of perspective. Some people look past it mostly because they want it so bad. I teased myself with it for about 7 days and finally made a decision that it could wait (mostly because the backlight bleed became worse!)

Exactly. The question is, would have anyone noticed if they were not looking for it? It's a psychological question I often ponder. I almost forgot about my backlight bleed because I really didn't experience it during normal lighting conditions and apps/background not highlighting the bleeding. The tablet also is fricking amazing from head to toe with regards to functionality, ease of use, and performance.
However, its a shame as the backlight is turned up all the way when you first start the tablet. Since the startup screen uses a complete black backdrop the first experience a brand new Prime user will have (and yes you WILL have it) will be light bleed.
I will watch a lot of movies on in and for sure a dark scene cant be avoided and I even use an all black background or a black and white picture so its gonna be noticeable on my regular use including the fact that 85% of my usage will be in the bedroom with lights off.
I've had my prime for about 10 days. It's got what I would consider minor light bleed. When I first turn it on and it's going through the boot screens, there's noticeable bleed in the top right corner and along the bottom in several spots. However, when the homescreen comes up (even with a dark background - i.e. the ASUS live wallpaper at night), I can barely notice any bleeding at all.
So, I guess my point is, if you're using it with the lights off, your screen brightness will be at its lowest setting and hence light bleed should be barely noticeable if at all.
Meh still! 100 times better than my old windows 7 laptop. I look forward to using the tablet vs my desktop or laptop because the screen is so beautiful. I still think many of you like me are tech junkies and will buy the next greatest thing when it comes out...

I'm awre of that, I'm gonna use a totally black png image to check for lightbleeding if ever I decide to get one.
First two primes I owned, returned due to stuck pixels are HORRIBLE light bleed. 3rd one barely any bleed (slight amount in upper right hand corner, BCOK serial number. 4th and 5th prime, C10K serial numbers, zero light bleed. Very happy with them.
(reason for 3, one for me, my wife and bought one for my brother in law for his birthday).
So you have a C1 and no light bleed?
Light Bleed getting worse
Has anyone seen their light bleed becoming worse as time goes by? My Prime came and there was only a slight light bleed in the lower left corner and was only noticeable during boot. I have now had the Prime for 3 weeks and the Light bleed has gotten worse. I now have light bleed up the left side, across the bottom and up the right side. Is anyone else seeing this with their Primes?
Others also reported that its getting worse.
Mine has bleed, but the only time I ever notice is when it's booting. They all have some form. iPads have them also. Mine did.... it's the nature of IPS, apparently.
Enjoy your TF201, stop staring at a plain black screen.
Mine has just a bit of bleed along the bottom, not really noticeable and nowhere as bad as our TV. The top-right corner however, on the bootup screen and any solid black (does not show up in any other color ) has pretty bad bleed. I'm pretty sure this is down to only having pressure in the four places this screen does.
If I push the panel's corner in toward the glass in that spot the bleed disappears, and no amount of tightening on the nearest screw will help.
I have not noticed mine get worse in the two weeks I've had it, but I reseated all the screws and made sure they were snug...
I don't know... I've had mine for a week and I don't have any light bleed. None that I can notice at least..
SN: C10
The backlight bleed 'issue' is either hit or miss. I had a B1 grey for a couple of weeks before my C1 Champagne pre-order finally came in and the B1 had no backlight bleeding what-so-ever. My C1 has a small amount light bleed along the right side, which from the sounds of it is fairly common on the C1s.
In my opinion the backlight 'issue' is not that big of a deal. In my normal daily use it is something I don't notice at all. As others have mentioned if you do get one with light bleeding the only time you really notice it is on the boot screen.
As you can see on the screenshot attached, I get a pair of light spots [1] in the upper right corner of my screen of my newly acquired TFP.
I get these at boot or whenever this part of the screen is dark, eg when looking at a movie.
Has any of you the same “problem”? Is this to be expected? Or should I contact the tech support? [2]
Thanks in advance for your help!
[1] One blueish on top of one redish.
[2] But I don't trust Asus tech support as they already gave me blatanly innacurate infos, as explained here (see “Part 3”).
That's light bleed, and it's caused by the display being improperly mounted (some screws inside are not fastened properly). It's a common problem with the Transformer. It can be ok (I can live with mine, it's barely perceivable), or worse. Yours seems to be in the second category. I'd exchange if it's still possible. I had pretty severe light bleed on my first one as well (plus a stuck green pixel in the middle of the screen), and exchanged it.
I've got similar lightbleed on my lower left corner of the screen during boot up. It's similar to the size of your top 'bluish' bleed. No other bleed. Otherwise not affecting daily use. H
OK, that is not normal. You need to open it up or exchange it.
So… Asus told me to go to the shop with my TFP and exchange it. But the new one was even worse. I went back to the shop once again and ordered a third TFP. I got it yesterday.
It's the best TFP I got in my hand, I still have one clear spot of light bleed (landscape upper left corner) and a small fringe almost all around the screen. {weeping}
For the price this toy cost, I expected no light bleed but I don't know if I should try a fourth time, could get a worse screen.
don't stop until you're satisfied! let asus know the level of quality we demand!

I just played with a new 2012 iPad at Bestbuy. I set it to display a black image and it also had noticeable lightbleed. Nowhere near as bad as the photo in that first post, but still noticeable on a black screen if you look for it.
I think that most devices that make use of LCDs have some level of light bleed. Looking at my Dell laptop, my HP laptop, my Samsung and LG LCD tvs and my OG EVO 4G each device had visible lightbleed on black screens.
The only device I own that doesn't have light bleed is my Galaxy S2 (hooray for OLED )
As long as you don't see the light bleed when it use, I think it is something you have to learn to ignore. If the lightbleed is severe enough that you cannot ignore it, exchange it for another device.
FWIW I have very slight lightbleed in my top right corner. But I only ever notice it on the boot screen

We could think so, yes. But, as far as technology is concerned, it should be easier to avoid light bleed (good sealing) than to obtain a good contrast (molecular properties) with LCD. Contrast ratio grows higher and higher and, on the other heand and afaik, it's my first light bleed ever! I never ever witnessed it on the laptops, netbooks and high-end lcd screens I worked with. Tablets are “toys” but TFP (and iPad) are definitely high-end toys. Hence my dissatisfaction.

The lightbleed in your photo is very severe, and I wouldn't be satisfied with it. However lightbleed does exists on most LCD screens. I never noticed it on other devices until it was pointed out to me on my OG EVO 4G and now I see it everywhere.
Like I said, if the level of lightbleed that your device displays is too difficult to ignore, exchange it for a new one or for a different device. However the chances of you finding a device or any make or brand, that is 100% light-bleed free is very slim. This will be especially true since now you will be looking for it
I`m very happy with my prime, and apart from the gps it seems to be without faults. But the auto contrast is really annoying. I get why it`s on in powersaving mode, but it is still there, even in performance mode. Is there any way to turn it off? I hope this can be brought to Asus`s attention.

This might be what you seeing at work. Its a new innovative technology from nvidia implented in tegra3 for further battery savings. They have another feature they added also but can't find the description on it.
" NVIDIA PRISM Display Technology - PRISM (or Pixel Rendering Intensity and Saturation Management) reduces a mobile device’s backlight power while simultaneously enhancing the pixel color to deliver the same visual quality with substantially extended battery life."
I have never had an issue like you describe... anyone else? Is it happening more in bright situations or what?
I don't have anything like this. Do you have auto brightness turned on? Could it be tied to that?

Get out of powersave mode.
I have noticed this too. On several occasions I have noticed the screen getting brighter or dimmer for no reason. I have checked and the Auto Brightness IS off. It doesn't happen all the time but I have noticed it.
I have auto brightness turned off, and I sometimes get this problem while watching certain YouTube videos. I can't think of any specific ones off hand. It's pretty annoying. I always run in balanced mode.
Same problem here.
A really simple way to see that, is set the contrast to the minimal (like when in bed ) and watch any video the luminosity will flicker a lot.
It seems that starting from 25% luminosity this effect is way less visible (even if still here).
Hmm... I've always had auto-brightness off and the display has never changed on its own.
But I usually have the brightness very low, and this may be my inability to notice these kinds of things.
Just did some testing, it's less visible when the brightness is turned up a bit, but still there. But I tried a regular movie, and I didn't notice it, but it was very obvious when watching anime. It happens in every power mode. I guess I can live with it if it's only visible when watching anime though...

yeh, I guess that's it. I wish they would implement a way to have it disabled in performance mode at least.
Sent from my Transformer Prime TF201 using xda premium
I wonder if it's hardware related or software/driver related. Hopefully in future rom developers find a way how to disable it because it's really really annoying.
The best way to see it is to turn your brightness all the way down, go into a dark room, and play a YouTube video. You'll definitely see the contrast/brightness changing.

The above describes this issue perfectly. All the resets in the world will not fix it, I'm afraid. This is a "feature" of the Tegra 3 chip to increase battery life. I have been experimenting with this extensively. You will notice this much more when brightness is set low (in my case, below 20% or so). It is especially evident in large white or light grey areas of the screen. You will notice what looks like automatic readjustments of the brightness of these areas. It will appear as though the screen is the automatically increasing and decreasing brightness - and the effect is by no means subtle. Try watching a video where there is a lot of white sky. Have a look at this video:
Search for Youtube Video "St Patrick Swipe" if you wish. Set your brightness at about 10%, with auto brightness off. Ensure you are in Balanced power mode or Performance power mode (the effect is very evident in Powersave mode if you want to try that, but I guess that is to be expected). Switch the video to full screen and go to point 1:53 and watch as the two guys go through the gate and up the hill (until about 2:12). You should see the video darken and lighten noticeable (thanks to the good old grey Irish sky!).
For me, this is a show stopper. It means I cannot watch videos at lower brightness levels, when the effect is more noticeable. It also means that when browsing web pages (which have white backgrounds), I am constantly seeing this contrast readjustment and it is very annoying and distracting. I really wish I was the kind of person who notice this kind of thing, as I'm sure quite a few may not. I am returning this otherwise fantastic tablet because of it.
Yes, I know this is my first post and will probably be deleted (you guys are strict!), but I've been reading about this problem here (there are plenty of threads) and in other forums and just wanted to add my voice.
I noticed this the other day whilst watching this YouTube vid in bed with the brightnes low.
http://www.youtube.com/watch?v=uMm9E8pGZ7M&feature=youtube_gdata_player
It'd be a little better if it was a subtle change, bithgening ad dimmming slowly rather than the abrupt increase/decrease in brightness. It'd be even better if it could be disabled altogether but at least I know it's not a fault with the TP and is in fact a feature.
Thanks for putting my mind at rest everyone, I'll live with the annoyance.
I also really wish this could be disabled. It is very very noticeable when watching anime. Keeps changing from bright and vibrant to dark and dull

Just a quick heads-up: In the Acer Iconia A510, also a Tegra3 tablet, this issue does NOT occur.
So it's not a hardware thing and Asus needs to fix this
Could the problem be the proximity of the light sensor near the screen? Maybe it's bleeding light into the sensor.
i myself is having this issue, and i see it constantly cause it affects my eyes alot, my eyes feel like its re adjusting to the dark and brighter setting when it happens so i notice it instantly, i really do wish that it would stop, cause its hurt my eyes at night when the screen gets brighter, i think its affected by whats being displayed on the screen, if something is really too bright, it dims it and if something is too dark it brightens it but for gaming and viewing movies that can get very annoying since movies and gaming changes scene very often.

Does anyone have both the TF 101 and the prime? I had gotten a replacement from Asus, and I noticed the screen would wash out a lot more on an angle compared to my TF 101, So asus replaced it (the first replacement was a C30 and they replaced it with a C20 which actually has better wifi range than the C30 did) And I noticed again that the screen would wash out more when held on an angle than the TF 101 did. Now I dont think I got two primes with the same exact issue so now I'm thinking that maybe its just the way the TFP LCD panel is. So I was wondering if someone that has both a TF101 and a Prime if they can do a side by side and let me know. Put the same wallpaper on both devices, and also set the brightness to the same on both devices(I set them both to max, with IPS+ off on the prime). Does the prime get more washed out when held on an angle compared to the TF101?
Thanks in advance
Put the Prime in Performance Mode and then re-do your testing.
Its an auto contrast feature of the tegra 3. Seems to happen more in lower power modes. Search for contrast on this forum there posts about it but its a feature not a bug. Higher brightness and super ips mode are also ways to reduce it from happening.
Oh yea and the 101 didnt have this feature.

Thanks, I was looking at that but wasnt sure if it was the same issue. I do notice the TFP washes out a lot more on an angle even when in performance mode. Since I got two replacements that were like this I'm thinking more its just the way it was made. When asus sent me the first replacement and I noticed it(I dont think I noticed it on my original TFP) I took a video of it washing out more compared to the tf101 when viewed on an angle. I'm pretty disappointed.. I have never seen an IPS screen wash out like that. It washes out on an angle more than my HTC Evo View(flyer) and that's not even an ips or slcd screen
Here are the links of the videos of the first replacement they sent me. This new replacement washes out the same way on an angle

I have both, and don't notice any difference except the 201's screen is much sharper and way brighter. I hack the 101 with revolver, and have left the 201 stock. Just got the GPS kit, and now get more sats with the 201 indoors! Too bad the GPS kit doesn't have a power jack. My 201 is a BCOKAS.
If those videos are accurately showing what you're seeing with the device in-person, then I would exchange the unit again. Mine looks nothing like that. Like others have said, the viewing angles on my TF201 are just as good as on my TF101. I'd say the Prime's screen is an improvement in every way, and I thought the original Transformer had a very nice screen.
What you are seeing is Light Bleed, you can search in XDA how to fix it yourself (you have to open your Prime) or return it to Asus. That is not how the screen should look.

Yeah, thats the way it looks in person. I really doubt asus will replace it a 3rd time... I'm waiting to hear back from Hai Trat. I expected the viewing angles to be the same as well. when I wish I could remember if my first unit washed out.. I think I was too anal about the dead pixels it had to notice if that one washed out. But after getting the 1st replacement and the 2nd and both washed out like that and both were different batches (first replacement was a C3, 2nd was a C2) I figured maybe it was normal. Guess not..

Nope, it's not light bleed. That unit does have some but the video shows it correctly, when viewed on an angle the whole screen clouds and washes out. And this is the 2nd one that has done this. My tf101 has some light bleed and doesnt do that at all. This 2nd replacement I have (the video is of the 1st one) the backlight bleeding isnt as bad and it still washes out like that on an angle.
Hmmm....Now that I do a direct side-by-side...in a dark room, with dark backgrounds on both tablets...I do see more of that "glow" that you're showing in your videos. The image is still crisp, but there is a distinct white-out, glow kinda thing going on. Maybe not quite as pronounced as your video, but that could just be lighting, camera, etc.
I probably wouldn't have noticed without doing the side by side video to see if I could show you how mine was OK, lol. LIke I said, the image and colors are still crisp, but there is a bit of that glow over the image.
I almost wonder if it isn't the oleophobic coating refracting the light. It's definitely not just general backlight bleed. My Galaxy Nexus (which also has an oleophobic coating of some kind) doesn't seem to exhibit the same off-axis behavior, but the screen is OLED, is much smaller, etc, so it's hard to make a direct comparison.
Your videos did seem pretty pronounced though. At this point I can't comfortably say one way or the other. I still think my screen looks great. I guess you just have to figure out if you're satisfied or not. In comparison to my TF101, I'd pick my Prime's screen every time.
